    To evaluate the role of hyaluronic acid (HA) filler injection in the management of upper eyelid retraction (UER) in thyroid eye disease (TED). Retrospective interventional series of all patients with TED who had undergone HA injection, from February 2011 to April 2013 by a single surgeon (Y-DK) in a tertiary medical institution. Outcome measures: Mean margin reflex distance 1 (MRD1) pre- and post-filler. There was a total of 13 patients and 17 eyes included in the study. The injection dosage for 15 eyes was 0.5 ml, one patient had 0.35cc on the right eye and 0.65cc on the left eye. Mean MRD1 at presentation was 6.21 mm. There was a mean decrease in MRD1 of 2.01 mm (p < .001) at 1 month post filler, 2.06 mm (p < .001) at 6 months post filler and 2.61 mm (p < .001) at 1 year post filler. There was no correlation between pre-filler MRD1 and change in MRD1 at various time points post-filler, nor any correlation between pre-filler upper scleral show (USS) and change in USS post-filler. There was also no correlation found between clinical activity score (CAS) and change in MRD1, as well as duration of thyroid eye disease (TED) and change in MRD1. Complications included mild upper lid lumpiness on downgaze (n = 4, 23.5%) which improved but persisted with time. There were no untoward intravascular or vision-threatening complications. Transconjunctival HA injection is an effective treatment option for TED-related UER in both active and inactive TED patients in an East Asian population, with a potentially long-lasting effect.
